  • Water repellent mesh – for minimal wet weight.
  • Quick drain zones – to help pump the water out with each foot stride when you hit dry land.
  • Sticky orange rubber FG sole with low-profile lugs – for wet/dry rock grip and partner visibility when you're on the swim section.

Comfortable straight out of the box

As I have come to expect with vivobarefoot designs these were Comfortable straight out of the box. Only drawback so far is the black colourway made my feet very hot wearing them on a sunny day. Just started wearing them so I cant comment on how they would work in a long distance race but its promising and the sole grip design is more stable on tarmac than my current swimrun choice.

Nice shoes and they look great. I am normally a size UK9 but I needed UK10 in these which give me 2cm toe space with out insoles and 1cm with. They are very light and tighten just right with the quick lace system so that they hug my feet with just the right amount of pressure. I have used them on mixed terrains and wet and dry conditions and the grip is good. They lose water very quickly and stay comfortable. I haven't been for a swim in them yet but can't wait to give them a go when I get to a beach.
